desktop: build with amalgamated maplibre native

[VaibhavNalawade]

What happened?

I think u need to embed this lib possible as this issue gone plague on Linux system

Affected Platforms

• Android
• iOS
• Desktop (JVM)
• Browser (JS)
• Browser (Wasm)

Platform Version

Arch Linux

Library Version

0.11.1

Sample Code

MaplibreMap(modifier = Modifier.size(300.dp))

I think we can fix this by building / using the amalgamated native core (#586)

I have a similar issue on MacOS

Exception in thread "main" java.lang.UnsatisfiedLinkError: Native library not found in JAR: /macos/aarch64/metal/libmaplibre-jni.dylib at org.maplibre.kmp.native.util.SharedLibraryLoader.extractAndLoadLibrary(SharedLibraryLoader.kt:57) at org.maplibre.kmp.native.util.SharedLibraryLoader.load(SharedLibraryLoader.kt:81) at org.maplibre.kmp.native.util.AutoCleanPointer.<clinit>(AutoCleanPointer.kt:19) at org.maplibre.kmp.native.map.CanvasRenderer.<init>(CanvasRenderer.kt:16) at org.maplibre.kmp.native.map.MapCanvas.addNotify(MapCanvas.kt:44)

Everything works fine in the sample project but when the library is used in another project it fails on MacOS. Should I manually copy "maplibre-native-bindings-jni" part to my project or should I publish it to MavenLocal? What is the right option?

This error looks a bit different. What does your build.gradle.kts look like?

Here it is (it's a separate module for desktop):

Looks like you've missed the natives dependency. See https://maplibre.org/maplibre-compose/getting-started/#set-up-desktop-jvm

OK. I see.

I tried to add them before but they've resulted in the following error:

> Unable to find a variant with the requested capabilities: [coordinates 'org.maplibre.compose:maplibre-native-bindings-jni-macos-aarch64-metal', coordinates 'org.maplibre.compose:maplibre-native-bindings-jni-linux-amd64-opengl', coordinates 'org.maplibre.compose:maplibre-native-bindings-jni-windows-amd64-opengl']:

However it runs fine using the following options (linux and windows commented out):

runtimeOnly("org.maplibre.compose:maplibre-native-bindings-jni:0.11.1") {
                    capabilities {
                        requireCapability("org.maplibre.compose:maplibre-native-bindings-jni-macos-aarch64-metal")
                        //requireCapability("org.maplibre.compose:maplibre-native-bindings-jni-linux-amd64-opengl")
                        //requireCapability("org.maplibre.compose:maplibre-native-bindings-jni-windows-amd64-opengl")
                    }
                }

Thanks!

Ah yeah we should update the docs; they're a bit misleading.

You need to pick one variant for the platform you're building for. So uncomment the one you're building, or detect os/arch in the build script using OperatingSystem.current() and System.getProperty("os.arch")
